The Kentucky Flintlock Rifle is prominantly seen in the hands of the defenders of The Alamo, and is the only identifiable flintlock rifle used in the film.
Officers in the film keep dress officer's Flintlock Pistols in cross draw holsters throughout the film. Jim Bowie (Richard Widmark) holds a smaller model on Colonel Davy Crockett (John Wayne) before he takes it from him. Bowie is also seen wielding two pistols during the last stand. Colonel William Travis (Laurence Harvey) also wields one during the fighting.
Jim Bowie (Richard Widmark) carries a 7-barreled Nock Gun as his main weapon in the film. This gun could be considered an old-day shotgun, although it was ironically designed as a marksman's rifle. The combination of seven smooth bore barrels unevenly placed in a "honey-comb" formation made the rifle extremely inaccurate (which led to it quickly switching from a marksman's rifle to a volley gun) and the immense recoil of the seven barrels all firing at once was unpleasant. On top of that, the rifle was rather heavy and took far too long to reload and was thus never popular in combat use.
Some soldiers defending The Alamo use Trapdoor Springfield 1873 rifles mocked up as flintlock rifles, likely due to the ease of using metallic blanks cartridges instead of blank shot.
